L92 Heads with LS3 intake valves, exhaust? I have an LS3 short block with LS6 top end, it ran great, until one of the CNC heads cracked. I have a set of L92 heads that I bought several years ago. I am seeing that I need to replace the heavy intakes with LS3 hollow valves, what about exhaust? They have to be lighter than the intakes, will the L92 exhaust valves work in a road race car? Is there any benefit to swapping for LS3 exhaust valves ?

Correct about the intake valves and the exhaust are pretty cheap. If you want something even lighter Re sized Ls7 valves are great for around a 100 bucks each, been thinking they would make a good 2 time Layaway plan $50+$50. Pay J one week pick them up the following week sounds pretty good to me. Until they are acquired. Just left the shop and asked this same question.
